Tanaka was scheduled to start Wednesday against the Rays, but Michael Pineda will likely get that start now. Pineda will be working on regular rest. He was scheduled to get two extra days off this week.

The Yankees are planning to recall infielder Gregorio Petit from Triple-A Scranton/Wilkes-Barre when Tanaka is placed on the 15-day disabled list.

Tanaka, 26, owns a 3.22 ERA, a 0.94 WHIP and a 24:7 K:BB ratio in 22 1/3 innings this season. He was pitching through a partial tear in the ulnar collateral ligament in his elbow, an injury he suffered last season.
